[CLOSED]Ext 4 Themes

hi team,

it's a bit sad that all the examples use the ext js 3 - default theme (only slight changes).
we have a folder:

resources / themes / images / default

which contains lots of images, no other folder for other themes.
Do we need to create those images for new themes as well for non css3 fallback or are they auto-generated? quite a difference regarding creating new themes.

i remember from the conf. the statement, that ext4 would need almost no more images...

in resources / css we have ext.css and ext4.css.
if i include the ext4.css instead the other one, nothing gets rendered properly anymore.
